The gas co2 is diffusing at steady state through a tube 0.20 m long having a diameter of 0.01 m and containing n2 at 298 k. the total pressure is constant at 101.32 kpa. the partial pressure of co2 at one end is 456 mmhg and 76 mmhg at the other end. the diffusivity dab of co2 in n2 is 1.67 × 10−5 m2/s at 298 k. calculate the flux of co2 in (a) cgs and (b) si units for equimolar counterdiffusion. note: gas constant = 82.057 cm3 atm/mol k. the answer is 1.71 × 10−7 mol/cm2 s = 1.71 × 10−6 kmol/m2 s, but i cannot figure out how to get
